A bstract : A dynamic metric for near‐Earth object (NEO) hazard mitigation quantifies threats from potential NEO impacts with Earth in terms of energy required to perturb threatening NEO orbits to avoid collision. The required energy is based on NEO mass, anticipated velocity change to avoid collision, and the momentum coupling coefficient.
